'Ehe wheel 13 of the lower .feed roller meshes with an idler gear wheel19 which in turn meshes with a wheel 2O on the shaft 0'5": the take-uproller. The feed rollers are actuated hy the original sheet as it isdrawn forward across the writing bed and there fore, by means of thetrain of geeringjnst hereinheore described, motion is imparted. to thetake-up roller so -that the copy sheerl is Wound thereon after passingaround the guide roller 13.

The feed rollers are held toward one unother with a yielding pressure hymenus et a tension lever pirotully Connected nt one end as at 23 to then'iuchine traine und hui'- ing connected to its opposite end u tensionspring 24 having its other end connected with the machine frame, saidlever heuring against the shaft of the upper feed roller so as to pressthe upper feed roller Iii-inl)Y toward the lowerI feed roller. ri`hehearing; hole for the shaft of the upper feed roller is verticallyelongated to permit the action just described. After the copy sheet hasbeen wound upon the trike-up roller, the copy sheet may he removed bysliding,r the shaft of the take-up roller endwise out of the traine inwhich it is supported, this heing accomplished hy rocking u latch lever25 pi'voted at :2G on one of the side plates of the machine frame undhaving :i hole 2i' through which the shaft of the take-up roller isadapted to he withdrawn, carrying with it the geur wheel 9.0.

rIhe shaft il of the take-up roller is reduced ns shown et QS to t'orinu shoulder 2S adapted to be engaged bfi the lower extremity of thehitch. lever, und the hitch lei'er is held in locking engagement withsaid shoulder by ineens of u, spring 30 having one end connected to theupper urin oi the liieli lever und the other end uttucled to the freineof the machine.
